-THEFTPREVENTING MEANS FOR VEHICLES.

To all whom it may concern:

Be it known that I, MIEOZYSLAW J. SZAMEIT,- a citizen-of the UnitedStates, re-

sidin at Chicago, in the county of Cook and tate. of Illinois, haveinvented a new and useful Improvement in Theft-Preventing Means forVehicles, of which the following is a specification.

My invention relates more particularly to vehicles employing internalcombustion engines as the motive power for the same and my primaryobject, generally stated, is to provide a novel, simple and economicalconstruction of means for preventing the theft of vehicles, which may bereadily placed in and out of operative condition at the will of anauthorized person.

As a premise to the following description,

it may be stated that my invention operates on the principle ofarresting the flow of fuel for the engine, as for example, gasolene.

Referring to-the accompanying drawings, Figure 1 is a broken viewshowing the pipe which leads from the gasolene supply to the carbureterof a vehicle, as for example an automobile, with theft-preventing -meansembodyingmy invention, interposed in said conduit, the said means beingshown in longitudinal section, the section being taken at the line 1 onFig. 2 and viewed in the direction of the arrow. Fig. 2 is a sectiontaken direction of the arrows, these two views showing the device in theposition it-assumes when in a position for arresting the flow ofgasolene through the conduit; and

Fig. 3, a view like Fig. 1, showing the device moved to a position inwhich the flow through the conduit is not interrupted.

The device, as constructed in accordance with the preferred embodimentof my invention, comprises a casing 4 containing a longitudlnallyextendln chamber 5 contalnmg openlngs 6 and F 1n opposite walls whichopen into this chamber and into nipples 8 into" which the pipes 9forming the conduit leading from the fuel supply to the interior of theengine, are. screwed. The

. chamber 5 contains a longitudinally movable valve member 10 whichsnugly, yet slidingly,fits this chamber and contains an opening 11therethrough which registers with Specification of Letters Patent.

Application filed January 18, 1918. Serial No. 212,392. a

the openings 6 and 7 when the valve member 10 1s 1n lowermost positionas hereinafter described. Spring mechanism represented at 12 andpreferably formed of a pair of splral springs, is located within thelower end of the chamber 5 and interposed between the bottom of thelatter and the bottom of the valve 10, this spring mechanism serving tonormally hold the valve 10 in raised posltlon as represented in Figs. 1and 2, and to retur11 it to this position after force applied theretofordepressing it, has been removed. i It will be understood from theforegoing that when'the valve 10 is in the position shown in Figs. 1 and2 the conduit 9 will be closed thus arresting the flow of fuel to theengine and preventing the operation of the car, but when depressed tothe position shown in Fig. 3, against the action of the springs 12, itdoes not interfere with the flow of fuel through the conduit.

Any desirable means of control by the operator, may be provided fordepressing the valve 10 and holding it in open position, but it ispreferred that means of the general construction illustrated beemployed, a description of these means being as follows:

Surmounting the casing 4, the top of this casing being preferablyprovided with a continuous flange 13,.is a lock 14c of the Yale type,this look comprising a casing 15 containing a cylindrical bore 16, abarrel 17 rotatably confined in the bore 16 and the usual tumblermechanism involving the segmental tumblers 18 and 19 arranged in aseries in channels 20 and 21 in the casing 15 and barrel 1'?respectively, backed up by coil springs 22, and with balls 23 in thebores 21.

The lock 15 is secured to the flanged end of the casingt by screws 24and the barrel 17 is confined in the bore 16by means of the flanges 25and 26 on the barrel 17 the flange 26 being in the form of a washersecured to 'the bottom of the barrel 17 as by the it forces the valve tothe open position in Fig. 3, the adjacent ends of the tumbler section 18and 19 of all the series will extend in alinement with the oint betweenthe wall .of the bore 16-and the barrel 17 as shown in Fig. 3,therebypermitting the barrel to be rotated by the key to a position in whichthetumbler sections 19 oppose the unperforated portion of the wall ofthe bore 16 :in which position of the parts the valve 10 is held indepressed condition as the key cannot be forced from the key-Way 28,until the operator returns the barrel 17 to normal position. i 7

'It will be readily understood from the foregoing that mechanismconstructed in accordance with my invention may be readvention, it beingmy intention to claim my invention as fully and completely as the priorstate of the art will permit.

What I claim as new and desire to secure by Letters Patent, is
